"Harbeth and some other speaker makers use supertweeters that provide >20khz ultrasonic frequencies and supposedly provide more 'air' and a more 'realistic' and 'human' sound by making it better able to produce the leading edge of each transient without time smear but being neither a firm believer nor a denier but a supertweeter agnostic...well, I have no idea what others can or can't hear"

Super-tweeters and tweeters extending well beyond 20 kHz were a big thing back in the 1970s and early 1980s, prior to the CD era..... (Even Radio Shack was marketing such products.) As were "high speed" and "wide bandwidth" amplifiers..... But the bandwidth limitations and HF artifacts from CD playback made these products less desirable..... And unlike vinyl playback, super-tweeters and wide-bandwidth amplifiers didn't make much of a comeback, mainly because they don't do particularly well with digitally-sourced audio.
